Five crushing advantages of PF series impact crusher
PF impact crusher is widely used in various ore crushing, railway, highway, energy, cement, chemical, construction and other industries. The impact crusher has such a wide range of uses because it has the following 5 major crushing advantages. Click to view the detailed introduction of the impact crusher.
1. The impact crusher can effectively process materials with large moisture content and prevent the blockage of the crusher
When the water content of the processed material is too large, the feed chute and the impact plate of the impact crusher can be equipped with a heating device to prevent the material from sticking. The impact crusher does not need to be equipped with a bottom screen, which can effectively prevent clogging. The hammer crusher cannot use heating to prevent material sticking, and must be equipped with a bottom screen, which increases the possibility of blockage.
2. The impact crusher is suitable for both soft materials and very hard materials
The plate hammer of the impact crusher is firmly fixed on the rotor with a mechanical clamping structure, and has a large moment of inertia when rotating with the rotor. Compared with the hammer crusher (the hammer head is in a hanging state), the rotor of the impact crusher has a greater momentum, which is suitable for crushing harder materials and has lower energy consumption.
3. The impact crusher can easily and flexibly adjust the discharge particle size with a wide adjustment range
The impact crusher can adjust the discharge particle size in many ways, such as adjusting the rotor speed, adjusting the gap between the impact plate and the grinding chamber. The gap adjustment can be adjusted mechanically or hydraulically, and the hydraulic adjustment system can be used to easily complete the gap adjustment through the on-site operation button or the travel control system. The hammer crusher can only adjust the discharge particle size by replacing the bottom sieve plate.
4. The wear of the vulnerable parts of the impact crusher is smaller than that of the hammer crusher, and the metal utilization rate is higher
The wear of the hammer of the impact crusher only appears on the side facing the material. When the rotor speed is normal, the feed material will fall to the surface of the blow hammer, and the back and sides of the blow hammer will not be worn. Even the wear on the side facing the material is very small. And the bottom grinding rod is easy to replace. The metal utilization rate of the impact crusher plate hammer can be as high as 45%-48%. The hammer head of the hammer crusher is in a hanging state, and the wear occurs on the top, front, back and side. Compared with the plate hammer, the hammer head wears more serious, and the metal utilization rate of the hammer head is only about 25%. Moreover, the rotor body itself may also be subject to wear. The sieve plate at the bottom of the hammer crusher is seriously affected by abrasion, and all the grilles must be replaced, and the replacement of the sieve plate is also complicated.
5. The replacement of spare parts of impact crusher is easy and maintenance costs are reduced accordingly
Only 6 blow bars are installed on the rotor of the impact crusher. The blow bars can be easily replaced with special tools provided by Henan Dewo crusher Mining Machinery Company. It only takes one shift to replace a set of blow bars. The replacement of the grinding rod in the bottom grinding cavity also only takes tens of minutes, which greatly reduces the time and cost of overhaul and maintenance. The hammer crusher has more than 100 hammer heads. It takes a lot of time and manpower to replace a set of hammer heads, and the maintenance and maintenance costs are high.
